SPATIAL_FILTER

SPATIAL_FILTER

Name

SPATIAL_FILTER

Purpose

This function will return a response from the spatial filtering of a one-, two-,
or three-dimensional array with the provided one- or two-dimensional filter.
If specified, this routine will properly rotate the filter before performing the
filtering operation to perform pure mathematical convolution.

Category

Image Processing.

Calling Sequence

Result = SPATIAL_FILTER( array, filter [, /ROTATE] [, /VERBOSE] )

Inputs

array
A one-, two-, or three-dimensional array containing the data on which to
perform the spatial filtering.
filter
A one- or two-dimensional array containing the weights for the filter.

Keyword Parametrs

ROTATE
An optional parameter that if set will cause the filter to be
rotated before performing the filtering operation.
VERBOSE
An optional parameter that if set will cause performance timing
information to be reported to the console.

Return Value

Result is a double-precision array, the same size as the original array
that contains the response of the spatial filtering. The response will be
normalized by the weight of the filter.
